1. Warnings and Precautions for Safety

Please observe the following safety precautions in order to use safely and correctly the refrigerator and to prevent accident and danger during repair.

1. Be care of an electric shock. Disconnect power cord from wall outlet and wait for more than three minutes before replacing PCB parts. Shut off the power whenever replacing and repairing electric components.

2. When connecting power cord, please wait for more than five minutes after power cord was disconnected from the wall outlet.

3. Please check if the power plug is pressed down by the refrigerator against the wall. If the power plug was damaged, it may cause fire or electric shock.

4. If the wall outlet is over loaded, it may cause fire. Please use its own individual electrical outlet for the refrigerator.

5. Please make sure the outlet is properly earthed, particularly in wet or damp area.

6. Use standard electrical components when replacing them.

7. Make sure the hook is correctly engaged. Remove dust and foreign materials from the housing and connecting parts.

8. Do not fray, damage, machine, heavily bend, pull out or twist the power cord.

9. Please check the evidence of moisture intrusion in the electrical components. Replace the parts or mask it with insulation tapes if moisture intrusion was confirmed.

10. Do not touch the icemaker with hands or tools to confirm the operation of geared motor.

11. Do not let the customers repair, disassemble and reconstruct the refrigerator for themselves. It may cause accident, electric shock, or fire.

12. Do not store flammable materials such as ether, benzene, alcohol, chemicals, gas, or medicine in the refrigerator.

13. Do not put flower vase, cup, cosmetics, chemicals, etc., or container with full of water on the top of the refrigerator.

14. Do not put glass bottles with full of water into the freezer. The contents shall freeze and break the glass bottles.

15. When you scrap the refrigerator, please disconnect the door gasket first and scrap it where children are not accessible.

• Icemaker starts harvest process by sensing tray temp unless ice storage bin is full.

※ When the bin fills to the level of the optics sensors, the icemaker will stop making ice.

• Icemaker has a ejector and a heater for harvest.

• Ice cube surface is melted by the heater installed the ice tray and ice cubes are

swept for the ejector from the ice tray.

• Icemaker is filled a certain amount of water provided by flow sensor in water valve.

• If the water pressure is too low (under flow sensor pulse value 6), the icemaker

will not work.

• To operate the icemaker properly, water pressure of 20~125psi is required.

WARNING

!

※ Water Filter Operation Pressure : 30 ~125psi (207~862kPa, 2.1~8.8kgf/㎠)

※ If the water pressure exceeds 125psi, a pressure reducing valve must be installed. ※ If the water pressure is under 30psi, a booster pump must be installed.

• Icemaker starts harvest process by sensing tray temp if the ice bin is not sensed as full.

• When the bin fills to the level of the feeler arm, the icemaker will stop producing ice.

• Icemaker is filled a certain amount of water provided by flow sensor in water valve.

• If the water pressure is too low (under flow sensor pulse value 6), the icemaker

will not work.

• To operate the icemaker properly, water pressure of 30~125psi is required. ※ If the water pressure exceeds 125psi, a pressure reducing valve must be installed.

※ If the water pressure is under 30psi, a booster pump must be installed.

1) Input ‘Forced Comp On Mode’ at Control Panel. (

※ To force open the step valve for 2 evaporators in series: Press/hold “Refrigerator Temp” and Freezer Temp” buttons, then press “Light” button 5 times.)

Turn off a refrigerator after 10 Minutes to open STEP VALVE.

2) Remove retained refrigerant more than 5 minutes after turning off a refrigerator. (If not, oil will leak inside.)

3) Remove retained refrigerant by cutting first high pressure side (dryer part) with a nipper

and then cut low pressure side. (If the order is not observed, oil leak will happen.)

Be sure to replace dryer when repairing pipes and injecting refrigerant.

WARNING

!

Nitrogen blowing

Others

To avoid risk of electrical shock that can cause death or severe personal injury, disconnect unit from power before servicing unless tests require power.

Weld under nitrogen atmosphere in order to prevent oxidation inside a pipe. (Nitrogen pressure : 0.1~0.2 kg/cm2.)

1) Nitrogen only should be used when cleaning inside of cycle pipes inside and sealing.

2) Check leakage with an electronic leakage tester.

3) Be sure to use a pipe cutter when cutting pipes.

4) Be careful not the water let intrude into the inside of the cycle.

Items Precautions

1. Removal of

2. Nitrogen blowing welding

1) Remove residual refrigerant more than 5 minutes later after turning off the refrigerator. (If not, compressor oil may leak inside.)

2) Remove retained refrigerant slowly by cutting first high pressure side (dryer part) with a nipper and then cut low pressure side.

 When replacing a dryer :

Weld ①and② parts by blowing nitrogen (0.1~0.2kg/cm2) to high pressure side after assembling a dryer.

 When replacing a compressor :

Weld ③and④ parts by blowing nitrogen to the low pressure side. ※ Note) For other parts, nitrogen blowing is not necessary because it does not produce oxidized scales inside pipe because of its short welding time.

■ KEYPOINTING ■ Welding without nitrogen blowing produces oxidized scales inside a pipe, which affect on performance and reliability of a product.

 Pipe Connection :

Connect a “red” hose to the high pressure side and a “blue” hose to the low pressure side.

 Vacuum Sequence :

Open ①,② valves and evacuate for 40 minutes. Close valve ①.

■ KEYPOINTING ■

1) If power is applied during vacuum degassing, vacuum degassing shall be more effective.

2) Operate compressor while charging refrigerant. (It is easier and more certain to do like this.)

 Charging sequence :

1) Check the amount of refrigerant supplied to each model after completing vacuum degassing.

2) Evacuate bombe with a vacuum pump.

3) Measure the amount of refrigerant charged. → Measure the weight of an evacuated bombe with an electronic scale. → Charge refrigerant into a bombe and measure the weight. → Calculate the weight of refrigerant charged into the bombe by subtracting the weight of an evacuated bombe.

■ KEYPOINTING ■

1) Be sure to charge the refrigerant at around 25°C.

2) Be sure to keep -5g in the winter and +5g in summer.

※ Calculation of amount of refrigerant charged (Wc) Wc = Wa - Wb Wa : weight after charging

Wb : weight before charging ( = weight of an evacuated cylinder)

9-4. Standard Regulations for Heavy Repair

1) Observe the safety precautions for gas handling.

2) Use JIG (or wet towel) in order to prevent electric wires from burning during welding. (In order to prevent insulation break and accident.)

3) The inner case shall be melted and insulation material (polyurethane) shall be burnt if not cared during welding inner case parts.

4) The copper pipe shall be oxidized by overheating if not cared during welding.

5) Not allow the aluminum pipes to contact to copper pipes. (In order to prevent corrosion.)

6) Make sure that the inner diameter should not be distorted while cutting a capillary tube.

7) Be sure that a suction pipe and a filling tube should not be substituted each other during welding. ( High efficiency pump.)
